最近项目开发中需要子窗口和父窗口交互的内容,基本上无非就是把子窗口的信息传递给父窗口,并且关闭自己等等,或者是父窗口把自己的信息传递给子窗口等等。
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
1。父窗口传递信息给子窗口
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
看代码实例:
![](https://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif)
<script language=javascript>![](https://www.cnblogs.com/Images/dot.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
function outPut()
![](https://www.cnblogs.com/Images/OutliningIndicators/ExpandedSubBlockStart.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/ContractedSubBlock.gif)
{
//获取父窗口的文本信息赋值给text
var text = document.abc.text.value;
//打开子窗口,并且把操作句柄赋值给win变量,以下所有操作都是针对win对象的
var win = window.open("","mywin", "menubar=no,width=400,height=100,resizeable=yes");
//输出基本信息
win.document.writeln("<title>输出结果</title>");
win.document.writeln("你的信息是:<p>");
//输出从父窗口获取的信息
win.document.writeln(text);
win.document.close();
win.focus();
}
</script>
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
<form name=abc method=post>
<input type=text name=text size=50>
//调用上面的函数
<input type=button value=提交 onClick="outPut()">
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
</form>
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
2。子窗口传递参数给父窗口
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
我们对上面的代码进行改造:
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif)
<script language=javascript>![](https://www.cnblogs.com/Images/dot.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
function outPut()
![](https://www.cnblogs.com/Images/OutliningIndicators/ExpandedSubBlockStart.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/ContractedSubBlock.gif)
{
var text = document.abc.text.value;
var win = window.open("","mywin", "menubar=no,width=400,height=100,resizeable=yes");
win.document.writeln("<title>输出结果</title>");
win.document.writeln("你的信息是:<p>");
win.document.writeln(text);
win.document.writeln("<input type=text name=child value=子窗口信息>");
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
//对子窗口本身操作,使用self对象,对父窗口操作使用opener对象,这是关键
//把子窗口中表单的值回传给父窗口,取代父窗口表单以前的值,然后关闭子窗口
win.document.writeln("<input type=button value=关闭自己 onClick='window.opener.abc.text.value=self.child.value;self.close()'>");
//可以控制关闭父窗口
win.document.writeln("<input type=button value=关闭父窗口 onClick='window.opener.opener=null;window.opener.close()'>");
//刷新父窗口
win.document.writeln("<input type=button value=刷新父窗口 onClick='window.opener.location.reload()'>");
![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
win.document.close();
win.focus();
}
</script>
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
<form name=abc method=post>
<input type=text name=text size=50>
<input type=button value=提交 onClick="outPut()">
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
</form>
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
3。不是同页面的子窗口和父窗口交互
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
假设我们涉及到外部程序,比如php、asp等等,那么我们处理的可能是两个页面,比如,上传功能,我们就是需要打开一个新页面,然后再把新页面中的值传递给父页面。
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
局部代码实例:
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
<input type="input" value="" name="input_tag" id = "input_tag" onKeyUp="clearPreTagStyle()" size="40">
<input type="hidden" value="0" name="tagid" id="tagid">
<input type="button" value="标签" onclick="popUpWindow('tag.php?tag='+escape(document.tryst_form.input_tag.value))">
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
以上是父窗口的部分代码,里面的popUpWindow是封装好的window.open函数,所以理解面面的tag.php是另外一个页面就可以,我们需要把当前表单中的值提交给tag.php页面去处理。
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
tag.php部分代码:
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
查询标签结果:
<a href="#" name="tag_1">生活</a><a href="#" onclick="opener.document.tryst_form.input_tag.value = document.tag_1.innerHTML">加入该标签</a>
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
<a href="#" name="tag_2">生活秀</a><a href="#" onclick="opener.document.tryst_form.input_tag.value = document.tag_2.innerHTML">加入该标签</a>
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
这个就是我们的子窗口,我们要把tag_1和tag_2返回到子窗口中,虽然他们不是同一个页面。这里有个知识点,就是我们如何获取连接中的值,我们使用innerHTML属性:document.tag_2.innerHTML 这个就是我们获取了tag_2的值“生活秀”,我们也能使用其他方法获取,比如:document.all.tag_2.innerHTML,或者this.innerHTML就是指本身的链接的值。
![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
访问父窗口也是使用opener对象来处理:opener.document.tryst_form.input_tag.value,就能够改变父窗口的值。
